'. means of chains placed on the right and the left of the machine. These chains move under the thrust of a special device, on pulleys-secured to the two ends of the machine, and they are at times rendered idle by automatic stopping devices, during which inoperative or idle periods the various gas pipes act to fire, incinerate and calcine the mantles. While in action, the chains operate mantle supporting rods andmantle guiding rods, the ends of these rods working in upper guides during their movement toward the front of the machine, and'in lower guides during their movement toward'the' rear of the machine when-the supporting rods are each provided with a series of mantles. The displacement of the rods, fromthe upper guides to the lower guides and from the lower guides to the upper guides according to whether this operation takes place' at the front, inthe center or at the rear ofthe machine, is obtained by means of elevators located on the right and left hand sides of the machine. These elevators are actu' atedby members called cam rods which are susceptible of longitudinal movement in both directions. On the cam rod located on the right, for instance, and at the' level of the right handfront elevator,there is fixeda chain adapted to be wound on a drum mounted on the same axis as another drum having a greater diameter on which a chain is wound, the other end of which issecured to the rod of the elevator. It is evident that in each of its displacements, either forward or rearward, thecam'rod will cause by actuating the drums through the medium of the chains, either the lowering or raising of the elevator rod. Since the lattercarri'es a device; intended to grip andmaintain the end of a mantle supporting and guiding rod, it is therefore possible to displace the said mantle supporting and guiding rods from one set of guides to another. In the form of apparatus in which the different. elevators are driven by chains, it has been observed that owing to wear, expansion and other causes, the ends of the carrying and guldlng rods did not reach a positionfacmg the guides in a perfect manner after a certaintimeof operation of the machine.

The object of the present invention is to obviate the drawbacks which have beeniin dicated above. Thi'sobject is accomplished by an improved devlce or mechanism in which the elevator driving chains are replaced by rigid members designed to bring the ends of the mantle carrying rods and: mantle guiding rods exactly into the position that these rods should occupy in the upperor lower guides. f

The invention comprises, moreover, certain members actuated by'the cam rod, and designed to place and maintain the mantle supporting and guiding rods, above each of the gas pipes of the triple gas piping for mcmerating purposes.

Finally, it comprises means for stopping the cam rod so as to avoid backward movement thereof during any of the operations of the machine, either by the action of a spring or from any other cause. I The accompanying drawings show, by wav of example, these various devices.

Figures 1, 2 and 3 are front elevations of the raising or lowering devices for the front, center and rear elevators of the machine; Figs. 4, 5 and 6 are front and side elevations of these elevators. Fig. 7' is an elevation of the mechanism for supporting" the rods above the tripleincin'erating piping, while Fig. 8 is a plan thereof. Fig. 9 is an elevation of the stop for while- Fig. 10 is a plan thereof.

The mechanisms illustrated in Figs. 1, 2 and 3 are duplicated and located on both the right and left hand: sides of the machine, so as to produce by the displacement of the ends of the cam rods 1, an exactly similar movement; The description of the mechanisms at one side of the machine will, in consequence, answer for both sides Each of these cam rods 1 is supported at its ends by the brackets 2 (Fig.1) and 2 (Fig. Each of these brackets is provided with the cam" rod, 7

which the cam rod moves. The lower rollers are adjustable and steel blades or sheets 4 and 4 are fixed on the upper and lower faces of the rod ends in order to protect the same against wear.

On each cam rod 1, there are fixed the collars 5, 5' and 5", each of which carries at its lower end a pivot pin or the like upon which is mounted one end of a rod 6 whose other end is pivotally connected at 7 with an arm 8 mounted on the adjacent end of a horizontal rock shaft. In the case of the front device, this shaft is indicated by the numeral 9, and is journaled in brackets 10, one of which is shown. The rock shaft of the central device is represented at 9, and both this shaft and the shaft of the rear device are mounted and connected up in the same general manner as the front shaft 9. On the said front shaft 9 there is also keyed a lever 11 pivotally connected at 12 with the lever 13 secured at its other end, to the frame or head 14 adapted to slide on the rod 15 of the elevator. In the case where owing to wear, displacement of members, etc., the ends of the mantle supporting and guiding rods should not reach a place exactly opposite that of the guides, the frame 14 may be lowered by compressing to a slight extent the springs 16 and 16 without causing the displacement of the elevator. A stop 17 limits the length of the stroke of the frame 14.

The device indicated above for obtaining the lowering or raising of the mantle supporting and guiding rods, is particularly applicable to the front elevators of the machine. In the other elevators, the modification to be made consists solely in the mounting of the rods and levers 6 and 8, 11 and 13. In the center elevator, however, in or der to maintain a constant connection between each of the members and to facilitate the operation, it is advisable to dispose on the shaft 9, a drum 18 on which a chain ter minated by a counterweight 19, is wound. From the above it will be quite easy to understand the operation of each of these elevators. When under the thrust of the stopping device, the cam rod 1 advances in the direction indicated by the arrow a, the collar 5 moves forward with said cam rod and thereby causes the rod 6 to assume the dotted-line position 6 and the lever 8 to assume the dotted-line position 8. During this movement of the cam rod, the shaft 9 is rocked, thus swinging the lever 11 into the dotted-line position 11', said lever, in turn, forcing the rod 13 to descend and assume the dotted-line position 13. In this downward displacement, the elevator which maintained the ends of the rods in the upper guide, now causes the same to face the lower guide without allowing any deviation whatever to take place.

In Figs. 7 and 8, a safety device is illustrated, intended to obviate the inconveniences due to the continuous displacement of the rods. In fact, it has been observed that the mantle supporting and guiding rods were not always perfectly connected with each other when they appeared above each of the gas pipes or the triple incinerating gas piping, and that owing to this circumstance, accidents took place in the manufacture of mantles. To this end there are disposed at the level of each of the lower guides, above the triple incinerating gas piping, two bars 20'and 20 adapted to slide along each other with a slight amount of friction. These bars are supported at each of their ends by the levers 21, 21 and 22, 22 secured to the shafts 23, 24 and 25 mounted in the bearings'26 and 27. The shafts 23 and 24 are provided at their ends with toothed sectors 28, 28 adapted to be rotated under the action of the armor lever 29 fixed to the opposite end of the shaft 23, from that on which the sector 28 is mounted. A vertical rod 30 is pivoted at its upper end 31 to the arm 29, and at its lower end 33 to the arm or lever 32. This arm 32 is pivoted at 34 on the bracket 35 secured 40 secured on the cam rod 1. The tappets 41 are fixed on the bars 20 and 20 by means of screws. grip and maintain by approaching each other a supporting rod and a guiding rod for the mantles during the time necessary for the incineration of the same. This operation is efiected in the following manner:-The rods 6 are operated in the lower guide 0 and automatically place themselves above the triple incineration gas piping. At this moment, an idle period begins, initiated by the stop device, which leaves one mantle carrying rod and a guiding rod above one of the gas pipes. These rods being disposed in pairs they more or less contact with each other. It is therefore important to locate them parallelly. This result is obtained by the movement of the cam rod which carries the plate 40 along with it, thust shifting the finger 38 on arm 37 owing to the special disposition of the grooves or slot 39 and causing the said lever 37 to rock about its pivot 34, thereby lowering the arm 32 and the rod 30 connected thereto. The lowering of this rod causes the displacement of the toothed sectors 28 and 28 and therefore the mutual approach of the tappets 41 fixed to the parallel bars 20 and 20 which are operated by the levers 21 and 22 mounted on the same shaft as the toothed sectors. During the mutual approach of the tappets 41, the rods 6 are supported and These tappets are intended to into a slot 39 formed in a plate or member caused to assume the positions which they ought to occupy above each of the gas pipes. and the incineration of the mantles is obtained in a perfect manner,

The device for the automatic stoppage of the cam rod so as to avoid any back-ward movement thereof, is shown in Figs. 9 and 10, and is constituted by a lever 42 pivoted at 43 on the same shaft as the lever 44 which carries at its end the finger 45. The latter bears on a lever 46 keyed upon the same shaft as the lever 47 which forms part of the stoppage device for producing the idle period. This stoppage device corresponds, in the main, to that disclosed in the said Bonnet and Muller patent, above identified, the lever 47 of the present device answering to the lever 16 of the patented construction, as shown in Figs. 4, 4 and 4, and described in lines 23 to 82, page 3, of the patent. Referenee may be had to said patent for a complete understanding of the device in question. Upon the bracket 48 which carriers the shaft 43, a rod 49 is disposed, pushed by a spring 50 against the tappet 51 forming part of the lever 42. An arm 52 also carried by the lever 42 serves to control the height or extent of the stroke of the lever 42 by 00- acting with a screw 53 adjustably mounted on a boss carried by the bracket '48. Furthermore, upon the cam rod 1, a member 54 is fixed, designed to serve as a stop for the end 55 of the lever 42.

The device operates in the following manner:At the moment where the idle period device abandons the cam rod 1 and pushes the same in the direction indicated by. the arrow (1, the lever 47 is lifted in the manner described in said patent, and operates in its movement the lever 46 which is now lowered. The finger 45 not being any longer supported, both levers 44 and 42 "are displaced under'th'e action of the .tappet 51, and the part 55 now assumes a position behindthe member 54 thus rendering any backward movement of the cam rod 1, impossible.
